Meaningful Relationships

In this essay I will explore the possibility of an objective ecological ethics. To do this, I follow the embodied ethos of relationships: meaningful expression and mutual sharing occuring in living organisms and systems. Living beings on various levels of identity (cellular selves, individuals, and ecosystems) strive toward increased aliveness. They are self-healing, and generate meaningful relationships, all without the need or interference of human ethical thinking. Ecosystems tend toward complexity and organisms tend to avoid their own destruction. Both tendencies create “natural values” – values not extractable into abstraction, yet nonetheless fundamentally embodied in the actions of living beings and living systems. An ethics based on these principles (or insights) is inclusive in that it can be conceived as a sort of “poetic objectivity”. Here the ethically good is the increase in “aliveness”, which can be shared by other beings, and which is only possible as “being through the other”. Aliveness is ineffable and cannot be extracted analytically. Hence it is objective only in a poetic sense that can be shared through participation. An ethics of poetic objectivity leaves room to negotiate individual relationships and narratives while providing goodness as an encompassing context tuning into the degree of sharing and mutual inspiration to be more alive. The natural values generated by sharing transformative relationships produce the whole of nature as an “ethical commons”. Its principles can be instructive in reorganising human exchange on ethical and economical levels.

The Individual

Growth will be defined as that attribute of living organisms which is manifested by a change of size of the individual, and we shall first consider growth formulae and curves. If y represents the size of any individual at time t , and if the growth process is regarded as continuous, we may define the absolute growth rate as dy/dt and the specific growth rate (which represents the change in y for change in time per unit amount of y ) as 1/ y dy/dt . Any statement which relates the size or growth rate of an organism to other variables will be called a growth formula; such statements are usually expressed in mathematical symbolism. Many growth formulae have been published and they have been derived by one of three methods.

Insects represent more than half of all known living organisms in the world. Both human beings and insects share a common biodiversity and the influence of insects on human life is enormous. They share an intimate relationship in which human beings are both benefitted and harmed. Insects inflict harm by stinging, biting or transmitting diseases. Rarely, humans are harmed by inadvertently coming in contact with the toxin of an insect. Insect dermatitis is characterized by tingling and burning within 10 minutes of contact, and sometimes the incurred dermatitis is a self-healing condition. Such cases usually happen while asleep when there is a lag time between the crush of the insect and waking up in the morning. A case while sleeping, heard the insect fly around her bare chest, in summer time, and on waving it away instinctively while sleeping, and the insect had been crushed on her bare upper chest skin, incurring a subsequent skin reaction without the typical red bite mark followed by an evolving burning ulcerative skin lesion, that took a while to subside and heal completely. Key words: insect bite, crash, skin reaction.

Abstract As it is known, the immune system found in higher evolutional level biological organisms is a distributed and multilayered system that is robust and able to identify infectious pathogens, injury, diseases, or other harmful effects. Therefore, their properties and abilities — like self-healing or surviving — would be more advantageous in many mechatronic applications, where often are imposed robustness and also high reliability operation requirements. Founded by these observations, the paper is focused on modeling and simulation artificial embryonic structures, with the purpose to develop VLSI hardware architectures able to imitate cells or organism operation mode, with similar robustness like their biological equivalents from nature. Self-healing algorithms and artificial immune properties implementation is investigated and experimented on the developed models. The presented theoretical and simulation approaches were tested on a FPGA-based embryonic network architecture (embryonic machine), built with the purpose to implement on silicon fault-tolerant and surviving properties of living organisms.

AbstractOne of the peculiar aspects of living systems is the production and conservation of energy. This aspect is provided by specialized organelles, such as the mitochondria and chloroplasts, in developed living organisms. In primordial systems lacking specialized enzymatic complexes the energy supply was probably bound to the generation and maintenance of an asymmetric distribution of charged molecules in compartmentalized systems. On the basis of experimental evidence, we suggest that lipophilic quinones were involved in the generation of this asymmetrical distribution of charges through vectorial redox reactions across lipid membranes.

In the last decade and a half, thin film research, particularly research into problems associated with epitaxy, has developed from a simple empirical process of determining the conditions for epitaxy into a complex analytical and experimental study of the nucleation and growth process on the one hand and a technology of very great importance on the other. During this period the thin films group of the University of Chile has studied the epitaxy of metals on metal and insulating substrates. The development of the group, one of the first research groups in physics to be established in the country, has parallelled the increasing complexity of the field.The elaborate techniques and equipment now needed for research into thin films may be illustrated by considering the plant and facilities of this group as characteristic of a good system for the controlled deposition and study of thin films.

Electromigration Effect

Recently, the growth process and relaxation process of crystalline structures were studied by observing a SI nano-pyramid which was built on a Si surface with a UHV-STM. A UHV-STM (JEOL JSTM-4000×V) was used for studying a heated specimen, and the specimen was kept at high temperature during observation. In this study, the nano-fabrication technique utilizing the electromigration effect between the STM tip and the specimen was applied. We observed Si atoms migrated towords the tip on a high temperature Si surface.Clean surfaces of Si(lll)7×7 and Si(001)2×l were prepared In the UHV-STM at a temperature of approximately 600 °C. A Si nano-pyramid was built on the Si surface at a tunneling current of l0nA and a specimen bias voltage of approximately 0V in both polarities. During the formation of the pyramid, Images could not be observed because the tip was stopped on the sample. After the formation was completed, the pyramid Image was observed with the same tip. After Imaging was started again, the relaxation process of the pyramid started due to thermal effect.

Gaas On Si

Growth of GaAs on Si using epitaxial techniques has been receiving considerable attention for its potential application in device fabrication. However, because of the 4% lattice misfit between GaAs and Si, defect generation at the GaAs/Si interface and its propagation to the top portion of the GaAs film occur during the growth process. The performance of a device fabricated in the GaAs-on-Si film can be degraded because of the presence of these defects. This paper describes a HREM study of the effects of both the substrate surface quality and postannealing on the defect propagation and elimination.The silicon substrates used for this work were 3-4 degrees off [100] orientation. GaAs was grown on the silicon substrate by molecular beam epitaxy (MBE).
